I was reading a production brief when the rumor landed: a Green Lantern will appear in James Gunn’s next Superman film. You feel that small, immediate rearrangement of expectations. I want to walk you through why this matters.
The InSneider first reported that Aaron Pierre’s John Stewart — fresh from HBO Max’s Lanterns — is set to appear in Man of Tomorrow. io9 reached out to DC Studios for comment; I’ll flag any updates if they arrive. For now, this shift changes the playing field.
Photographers spotted Lex Luthor in a spacesuit, and that visual changed set expectations
On set imagery has already hinted that Man of Tomorrow will reach outward — not just in scale, but in tone. You should expect a cosmic story: David Corenswet returns as Superman, Nicholas Hoult is Lex Luthor, and Lars Eidinger plays Brainiac. If John Stewart appears, it signals DC Studios and co-president James Gunn are threading TV introductions into theatrical beats.
Will John Stewart appear in Man of Tomorrow?
The short answer from reports is yes — Aaron Pierre, who plays John Stewart in HBO Max’s Lanterns, is said to be joining Gunn’s sequel. The InSneider broke the scoop and io9 has sought confirmation from DC. Sources claim Pierre’s role won’t be a blink-and-you-miss-it cameo; he’s already had to turn down other jobs, according to Sneider.
Set photos show Superman and Luthor in suit rigs, a visual cue that stakes are expanding
The images of suits tell you the conflict will cross atmospheres and maybe star systems. Brainiac as the antagonist makes that obvious. I see this as a story that stretches Superman beyond street-level threats and asks him to scale up his alliances and enemies — which is why a Green Lantern makes narrative sense.
This is a move that feels like a silent fuse: a small reveal that promises a larger, noisier explosion when the film lands.
Who is playing Green Lantern in Man of Tomorrow?
Aaron Pierre is the name attached to John Stewart. Pierre shares screen credit with Kyle Chandler’s Hal Jordan in Lanterns, which debuts on HBO Max in August. Nathan Fillion is expected to appear as Guy Gardner in that series, but his status in the movie remains unclear.
The DC release schedule now reads like a highway of premieres and crossovers
HBO Max has been queueing major DC pieces this year while Warner Bros. and DC Studios plan theatrical beats for next year. Lanterns arrives on HBO Max in August; Supergirl follows June; and Man of Tomorrow starts filming in April with an eye toward a July 9, 2027 release.
James Gunn and Peter Safran have said they want an interconnected DCU. That strategy treats TV characters as movable parts that can be shifted into features when the map requires it — like a chess piece — and John Stewart is positioned to be one of those pieces.
When does Man of Tomorrow release?
The current schedule aims for July 9, 2027. Filming is slated to begin in April. If Lanterns lays groundwork this year, the movie might pick up threads or consequences directly from the series’ finale.
There are practical questions that matter to you as a fan and to the industry: how big will Stewart’s role be, will Hal Jordan cross over, and does this change the tone we expect from Gunn’s Superman? Aaron Pierre will also appear next year in Star Wars: Starfighter, which could affect availability and marketing sync. Nathan Fillion’s Guy Gardner, while anticipated for Lanterns, has not been confirmed for the film.
I’ll be watching how DC Studios and HBO Max stagger these reveals — it’s a strategy that asks audiences to follow several threads across platforms and seasons. You can feel the plan tightening, and whether that excites you or puts you on guard will probably determine how you read the next trailer.
Do you think John Stewart’s inclusion will raise the stakes for Gunn’s Superman, or will it muddy the storytelling map?
